Repository: ambari
Description
-------
Knox fails the restart during EU with error
"""
resource_management.core.exceptions.ExecutionFailed: Execution of 'cp -R -p -f
/usr/hdp/4.2.0.0/knox/data/. /usr/hdp/current/knox-server/data' returned 1. cp:
cannot stat '/usr/hdp/4.2.0.0/knox/data/.': No such file or directory
"""
This is because the common service Knox Py script assumes data dir is under
stack_root which is /usr/hdp by the time it's Knox to restart during EU. But it
also attaches the "current_version" obtained from command json file that points
to 4.2.0.0 (or 4.2.5.0-0000) for the migration cluster. So the result root dir
/usr/hdp/4.2.xxxx does not exist.
